* wpv_recursive_flatten_post_relationships
*
* Flatten a multidimensional array of Types post relationships
*
* After creating a multidimensional array of Types post relationships with wpv_recursive_post_hierarchy we use this function to flatten it
* and return the same structure as a string using specific signs for parent and adjacent relations
*
* @param $relations_array (array) multidimensional array of Types post relationships, following the format:
* Array(
* [father] => Array(
* [grandpa-one] => Array(
* [bisa] => Array()
* )
* [grandma-one] => Array()
* )
* [mother] => Array()
* )
* @param $low_level (string) auxiliar string containing the lower levels in recursion, defaults to ''
* @param $parent_sep (string) separator for parent relationships, defaults to ">"
* @param $adjacent_sep (string) separator for adjacent relationships, defaults to ","
*
* @return (string)
*
* @note this function is recursive
* @note the returning string has the format
* bisa>grandpa-one>father,grandma-one>father,mother
