Tahoe Code SVN development

1. Modify stress, modulus and energy density calculations to account for bond energy splitting for surface clusters

typo

add stress-free lattice parameter from the bulk model to the input parameters
of the surface model

added stress-free bulk lattice parameter as input parameter

Checking in files before updating code from Sourceforge. Updates include
using the asinh function instead of arcsinh in SSEnnLocDieterichT for
greater accuracy, and adding the ability to use a seed element for
homogeneous stress states.

deleted assemblying of C matrices into one matrix; some typos corrected

call c_ijkl() before c_UU1_ijkl(), c_UU2_ijkl(), etc., and call s_ij() before YieldF()

correcting array index

1. Updated FCC3D_Surf PK2 and energy density to use area normalizations

updates for compiling from command line
