ADCToolbox

Adds xy presets for plotres/plotressin, improves plotspec noise-floor estimation for highly non-coherent signals, and allows column-vector weights in bitchk.

Fix plotspec Nyquist bin handling

Added two functions for visualizing partial-sum residuals of ADC bit matrices: plotres, plotressin

- plotwgt: Added wgtsca and effres outputs
- adcpanel: Automatic maxCode calculation for bit-wise data
- wcalsin: Improve robustness under abnormal data

- Add function 'adcpanel' for automatic one-stop ADC data analysis! More on 'help adcpanel'
- Add auto mode for 'sidebin' option in plotspec

- Fixed some naming problems
- Add a new function 'plotwgt' to display the weighting of ADC code
- Improve display quality for 'errsin'
- Add an auto mode (now default) for calculating noise floor in 'plotspec'

Rename specplot -> plotspec, phaseplot -> plotphase to avoid name conflict.

The first formal release with complete documentation.

- FGCalSine now supports multiple datasets with different frequencies (see function notes)

- fix specPlot noise floor calculation
- add errHistSine input dimension check
