errcheck_wavparam: Error check wavelet transform parameters
In wsyn: Wavelet Approaches to Studies of Synchrony in Ecology and Other Fields

Error check the parameters scale.min, scale.max.input, sigma, f0

1	errcheck_wavparam(scale.min, scale.max.input, sigma, f0, times, callfunc)

`scale.min`	The smallest scale of fluctuation that will be examined. At least 2.
`scale.max.input`	The largest scale of fluctuation that is guaranteed to be examined
`sigma`	The ratio of each time scale examined relative to the next timescale. Should be greater than 1.
`f0`	The ratio of the period of fluctuation to the width of the envelope. Defaults to 1.
`times`	The times data were measured at, spacing 1
`callfunc`	Function calling this one, for better error messaging
