added values for pullout and shear resistance; added 'assess_name
= eta_R_tot'for tension/shear interaction
defined normal and gradient temperature loads inclusive instead of
exlusive
Merge branch 'master' of https://ale-x@github.com/simvisage/simvisage.git
corrected evaluation of 'k_alpha' for 'eval_mode = eta_nm'; distinguish
'n_Rd,c' and 'n_Rd,t' for normal force resistance (used in evaluation of
eta_nm; corresponds to simplified interaction diagram considering also
compression); some clean_up (sorting of evaluation cases, comments
added)
method 'plot_assess_value' added (can be used to plot both 'n_tex' or
'eta_nm')
method 'plot_assess_value' called
minor changes
added path to buttstrap_clamping
