/**
 * Takes the web request and looks for a "fields" parameter (otherwise deprecated "properties" parameter).
 * Parses the parameter and produces a list of bean properties to use as a filter A
 * SimpleBeanPropertyFilter it returned that uses the bean properties. If no
 * filter param is set then a default BeanFilter is returned that will never
 * filter fields (ie. Returns all bean properties).
 * If selectList is provided then it will take precedence (ie. be included) over the fields/properties filter
 * for top-level entries (bean properties).
 * For example, this will return entries from both select & properties, eg.
 * select=abc,def&properties=id,name,ghi
 * Note: it should be noted that API-generic "fields" clause does not currently work for sub-entries.
 * Hence, even if the API-specific "select" clause allows selection of a sub-entries this cannot be used
 * with "fields" filtering. For example, an API-specific method may implement and return "abc/blah", eg.
 * select=abc/blah//from  w w w  . j a v  a 2 s .  c  om
 * However the following will not return "abc/blah" if used with fields filtering, eg.
 * select=abc/blah&fields=id,name,ghi
 * If fields filtering is desired then it would require "abc" to be selected and returned as a whole, eg.
 * select=abc&fields=id,name,ghi
 *
 * @param filterParams
 * @param selectList
 * @return
