-------------------- * Can get set liquefaction criteria for element test using double or single amplitude strain * Can deal with loading a cpt file when the gwl level is not set * Added the ManzariDafaliasModel soil model * `big_f` added as a parameter in Boulanger and Idriss CPT analysis * fixed function to allow crr_n15 to be computed from q_c1ncs according to BI2014
0.6.15
-------------------- * Added back-calc of n1_60 from crr_m7p5 using bi2014 `calc_n1_60cs_from_crr_m7p5` * Added `sra.PysraAnalysis` and `sra.run_pysra` as ways to run an equivalent linear analysis using the PySRA package * Can set point of liquefaction in element test using single aplitude and double amplitude strain criteria
0.6.14
-------------------- * Added theory one and two layer transfer functions * Minor change to LSN calculation to not use the average depth between points * Added `run_pysra` to run a site response analysis and obtain ACCX, TAU, and STRS * Updated logic for handling FLAC fis file inputs
0.6.13
-------------------- * Fixed issue with creating ESP when cpt depths are irregular
0.6.12
-------------------- * Fixed issue with fitting 3- and 5-layer ESPs now uses median to find value of least deviations
0.6.11
-------------------- * Added MRD curves for clay * Fixed issue with fitting 5-layer equivalent soil profile (ESP)
