Detailed Description
An abstract base class for representing the element level computation performed within a finite element operator for modelling solid mechanics (elasticity/plasticity). This class just handles some of the data and operations that is required by both the linear and nonlinear mechanics operators to perform their respective element level computations. The actual computation is implemented in the apply() function in the derived classes.

Constructor. This builds the finite element shape functions. This reads the values for the following keys from the database object contained in the parameter object, params: 1) USE_REDUCED_INTEGRATION (false by default) 2) FE_ORDER (FIRST by default) - Order of the polynomial used in the shape functions. 3) FE_FAMILY (LAGRANGE by default) - Family of the polynomial used in the shape functions. 4) QRULE_TYPE (QGAUSS by default) - Type of numerical integration scheme used. 5) QRULE_ORDER (DEFAULT by default) - Order of the numerical integration scheme.
