s2Member will create the following variables (internally) for backward compatibility
with older versions of the software.

-----------------------------------------------------------------------------------------------------------

Here is a breakdown on each of these Variables:

	* `_s2member_seeking[post|page|catg|ptag|file|ruri]` = (Post ID, Page ID, Category ID, Tag ID, File, URI)
		Tip: `_s2member_seeking[file]` = (File path, relative to /s2member-files/, or your Amazon® S3 Bucket)
		Tip: `_s2member_seeking[ruri]` = (A base 64 encoded URI; only applies w/ Membership URI Restrictions)
		Tip: These array elements are mutually exclusive: [post|page|catg|ptag|file|ruri].
			Only ONE of these array elements (i.e., Content Types) will be specified.

	* `_s2member_req[level]` = a Membership Level # required for access (only applies to Membership Level Access)
	* `_s2member_req[ccap]` = a Custom Capability required for access (only applies to Custom Capability Restrictions)
	* `_s2member_req[sp]` = a Specific Post/Page ID required (only applies to Specific Post/Page Access Restrictions)
		Tip: `_s2member_req[level|ccap|sp]` are mutually exclusive Requirement Types.
		 Only ONE of these three elements will be passed in combination with:
		 	`_s2member_seeking[post|page|catg|ptag|file|ruri]`.

-----------------------------------------------------------------------------------------------------------

Additional Variables that might be useful to developers:

	* `_s2member_seeking[_uri]` = (A base 64 encoded URI; the URI they were originally seeking)
		Tip: this is ALWAYS passed through, regardless of which Content Type was protected.

	* `_s2member_seeking[type]` = (A string. One of: post|page|catg|ptag|file|ruri)
		Tip: this is ALWAYS passed through, regardless of which Content Type was protected.

	* `_s2member_req[type]` = (A string. One of: level|ccap|sp)
		Tip: this Requirement Type Variable is ALWAYS passed through.

	* `_s2member_res[type]` = (A string. One of: post|page|catg|ptag|file|ruri|ccap|sp|sys)
		Tip: Actual Restriction Type that's preventing access; may differ from `_s2member_seeking[type]`.
		Tip: Restriction Type `sys` Systematic (i.e., something s2Member protects automatically)
		Tip: Restriction Type `ccap` represents Custom Capability Restrictions by s2Member.
		Tip: Restriction Type `sp` represents Specific Post/Page Access Restrictions.
		Tip: this Restriction Type Variable is ALWAYS passed through.

* The use of MOP Vars is 100% completely optional (for advanced site owners).
