In this PR, I’ve implemented warning and error flags that seek to provide more feedback to the user regarding common errors and issues. The following flags/messages have been implemented into wecSim as part of this PR:

• Argument checks were placed in some functions (such as plotResponse, plotForces, etc) of the response and wave classes to provide context on the expected function inputs.
• Properties within the simulation and wave class were given more specific requirements (such as requiring a positive timestep value).
• Error message when non-hydro bodies are specified before hydro in the wecSimInputFile
• Warning message when waves.waterDepth is defined and there is an .h5 file present
• Error message when waveSpread does not sum to 1
• Error when the name or filename is not specified in the body, constraint, pto, cable, mooring, and ptoSim classes, which indicates to the user that the objects have likely been defined in the wrong order.
• Error messages when necessary parameters (such as cg and cb) are not defined for bodies based on type (hydro, non-hydro, etc)
• Warning messages when extra parameters specified that don’t affect result (such as cg and cb for hydro body)
• Warning message for STL greater than half the size of the domain and error message for when it is greater than the domain size
• Warning for noWaveCIC case that waves.T is not used
• Errors and warning messages for parameters needed for each wave type
• Warning message when simu.dtOut < simu.dt

I am working on more warning and error flags, but wanted to get a PR started here so that it can start to be reviewed.
