Directing class of FieldValueCache.
Manage storing and updating element data (elements of same dimension) to cache. We need only one shared instance of this class for all fields in equation (but typically for dim = 1,2,3).
IMPORTANT: Because there are combined bulk and boundary elements, we must use mesh_idx value to correct identification of elements.

This array provides indexes to FieldValueCache.
This one dimensional array behaves like two dimensional factually. Size is set to 'n_cached_elements * n_eval_points' and items are accessible through two indices:
1: Over elements holds in ElementCacheMap 2: Over EvalPoints for each element
Use always and only methods element_eval_point
for read and set_element_eval_point
(for write) to access to items!
Array is filled in those three steps: a. Reset - all items are set to ElementCacheMap::unused_point b. Used eval points are set to ElementCacheMap::point_in_proggress c. Eval points marked in previous step are sequentially numbered
