Thanks for making this PR. Is TINKERPATH the recommended environment variable name from the TINKER distribution or is it a custom name? Is your intention that the environment variable should override what is in the input file?

I think that typically, the environment variable is more "invisible" whereas command line / input file options are more explicitly set by the user. Could you switch the priority order so that the input file will override the environment variable? You can still get the behavior you want by leaving tinkerpath blank in the input file.

…ker openmm on GPU), and gas is not in keyfile name, then switch dynamic to dynamicomm (gpu dynamic program).

2)	If OPENMM_CUDA_COMPILER is detected in environment, for NPT dynamics, then add N to dynamic command string (program asks for output info from GPU).
3)	MUTAL and THOLE keywords are added to lines that include Polarization in them (latest analyze version), so these are excluded from parsing Polarization energy.
4)	Temperature is not printed out in latest version (or gpu version), but since it is constant in NPT/NVT, just append the constant temperature instead of parsing.
5)	Switch priority of original commit, if tinkerpath keyword is specified, this supersedes any TINKERPATH detected in environment.

Could you comment on this? Is "dynamic" supposed to be an environment variable too?

The default parameters are what's used if the user doesn't specify the option in the key file, so it doesn't need to be the most efficient, it only needs to be fail-safe.

Does the use of respa require any additional options in the key file, i.e. specifying the long and short timestep, or the subdivision of the long timestep to make the short timestep?

This seems to duplicate line 956, could the determination of dynamickeyword be moved "above" the "if nequil>0" block, so it doesn't need to be duplicated?

Is there some way to simplify this so that it doesn't check for OPENMM_CUDA_COMPILER twice (once when it determines dynamickeyword and again when it decides how to call TINKER?) Maybe you could make the N into a variable "dynamicsuffix" or something like that?

@bdw2292 I'm reviewing all the open PRs and this one is looking pretty huge at this point, and it contains lots of code. I do want to include your features into the master branch, but I'm not sure I can understand all your modifications on my own. Could we schedule a meeting sometime to go over what you wrote? You may feel free to ask your PI to join as well.
