CrystalPlasticityStateVariable

Description

CrystalPlasticityStateVariable represents a state variable, such as dislocation density in crystal plasticity system. The initial values of this state variable are either provided in the input file readInitialValueFromInline() or read from the file readInitialValueFromFile(). The state variable evolves as is the state variable evolution rate. The can have multiple components, such as where "" are the scale_factor and are the individual rate components.
