Detailed Description
template<class elm_type>
class FieldValueCache< elm_type >
Class holds precomputed field values of selected element set.
Every field in equation use own instance for every dimension of elements (typically 3 instances for dim = 1,2,3).

Data cache.
Data is ordered like three dimensional table. The highest level is determinated by subsets, those data ranges are holds in subset_starts. Data block size of each subset is determined by number of eval_points (of subset) and maximal number of stored elements. The table is allocated to hold all subsets, but only those marked in used_subsets are updated. Order of subsets is same as in eval_points.
