#9345: Add support for M component to WKT and WKB I/O

Milestone: To Be Determined | Component: geometry
  Version: Boost Development Trunk | Severity: Not Applicable
 Keywords: wkt,wkb |
-------------------------------------+----------------------------
 This task is related to [http://lists.boost.org/geometry/2013/11/2669.php
 Changes in WKB (read) behaviour proposal (WKT Part)] discussion on the
 list.

 We should try to add ability to consume/produce the M (measure) component
 from/to geometries encoded in OGC WKT and WKB formats.

 As Barend explained in the thread linked above:

> We drop the M anyway (currently).
> We cannot handle it because our Point Concept does not contain model-
 values.
> Something additional would be necessary to be able to assign
> it to the point in question (strategy? policy? assigner?),
> which can do with it what it wants.
> An easy option would be assigning the M to the third dimension
> (if any), and that is probably currently the case
> (I have to check).

 I think a form of user-defined data assigner, similar to dimension
 assigners, which uses can enable for adapted geometries would be useful.
