Detailed Description

Data structure for storing the 2x2 block matrix associated with the BDFRadDifOpPJac, I + gamma*hat{L}, where hat{L} is a RadDifOpPJac.

Specifically, the constructor here takes in the data structure used to store the 2x2 block matrix associated with hat{L}, i.e., [ d_E 0 ] + [ diag(r_EE) diag(r_ET) ] [ 0 d_T ] + [ diag(r_TE) diag(r_TT) ] and overwrites it to create ([I 0] [ d_E 0 ]) [ diag(r_EE) diag(r_ET) ]

([0 I] + gamma*[ 0 d_T ]) + gamma*[ diag(r_TE) diag(r_TT) ]

[ d_E_BDF 0 ] [ diag(r_EE_BDF) diag(r_ET_BDF) ] [ 0 d_T_BDF] + [ diag(r_TE_BDF) diag(r_TT_BDF) ]

Note: We store the data in the above format for two reasons:

1. It allows an operator-split preconditioner to be built, wherein the diffusion blocks must contain the identity perturbation since AMG is applied to them, and it's easy enough to add an identity perturbation on the fly to the reaction blocks when decoupled 2x2 solves are done on them
2. The modification that we make to the data means that our underlying RadDifOpPJac's apply will actually be an apply of a BDFRadDifOpPJac (we would have to write another apply routine if we also added an identity perturbation into the reaction block).
