/**
* Returns a post or posts based on supplied parameters.
* @todo <b>THIS CLASS SHOULD CACHE QUERY RESULTS!</b>
*
* @param array $paramarray An associative array of parameters, or a querystring.
* The following keys are supported:
* - id => a post id or array of post ids
* - not:id => a post id or array of post ids to exclude
* - slug => a post slug or array of post slugs
* - not:slug => a post slug or array of post slugs to exclude
* - user_id => an author id or array of author ids
* - content_type => a post content type or array post content types
* - not:content_type => a post content type or array post content types to exclude
* - status => a post status, an array of post statuses, or 'any' for all statuses
* - year => a year of post publication
* - month => a month of post publication, ignored if year is not specified
* - day => a day of post publication, ignored if month and year are not specified
* - before => a timestamp to compare post publication dates
* - after => a timestamp to compare post publication dates
* - month_cts => return the number of posts published in each month
* - criteria => a literal search string to match post content or title
* - title => an exact case-insensitive match to a post title
* - title_search => a search string that acts only on the post title
* - has:info => a post info key or array of post info keys, which should be present
* - all:info => a post info key and value pair or array of post info key and value pairs, which should all be present and match
* - not:all:info => a post info key and value pair or array of post info key and value pairs, to exclude if all are present and match
* - any:info => a post info key and value pair or array of post info key and value pairs, any of which can match
* - not:any:info => a post info key and value pair or array of post info key and value pairs, to exclude if any are present and match
* - vocabulary => an array describing parameters related to vocabularies attached to posts. This can be one of two forms:
* - object-based, in which an array of Term objects are passed
* - any => posts associated with any of the terms are returned
* - all => posts associated with all of the terms are returned
* - not => posts associated with none of the terms are returned
* - property-based, in which an array of vocabulary names and associated fields are passed
* - vocabulary_name:term => a vocabulary name and term slug pair or array of vocabulary name and term slug pairs, any of which can be associated with the posts
* - vocabulary_name:term_display => a vocabulary name and term display pair or array of vocabulary name and term display pairs, any of which can be associated with the posts
* - vocabulary_name:not:term => a vocabulary name and term slug pair or array of vocabulary name and term slug pairs, none of which can be associated with the posts
* - vocabulary_name:not:term_display => a vocabulary name and term display pair or array of vocabulary name and term display pairs, none of which can be associated with the posts
* - vocabulary_name:all:term => a vocabulary name and term slug pair or array of vocabulary name and term slug pairs, all of which must be associated with the posts
* - vocabulary_name:all:term_display => a vocabulary name and term display pair or array of vocabulary name and term display pairs, all of which must be associated with the posts
* - on_query_built => a closure that accepts a Query as a parameter, allowing a plugin to alter the Query for this request directly
* - limit => the maximum number of posts to return, implicitly set for many queries
* - nolimit => do not implicitly set limit
* - offset => amount by which to offset returned posts, used in conjunction with limit
* - page => the 'page' of posts to return when paging, sets the appropriate offset
* - count => return the number of posts that would be returned by this request
* - orderby => how to order the returned posts
* - groupby => columns by which to group the returned posts, for aggregate functions
* - having => for selecting posts based on an aggregate function
* - where => manipulate the generated WHERE clause. Currently broken, see https://trac.habariproject.org/habari/ticket/1383
* - add_select => an array of clauses to be added to the generated SELECT clause.
* - fetch_fn => the function used to fetch data, one of 'get_results', 'get_row', 'get_value', 'get_query'
*
* Further description of parameters, including usage examples, can be found at
* http://wiki.habariproject.org/en/Dev:Retrieving_Posts
*
* @return Posts|Post|string An array of Post objects, or a single post object, depending on request
