Correction of IQ impairments

Classes
class	gr::blocks::correctiq
	This block to removes that center frequency IQ DC spike with an IIR filter. More...
class	gr::blocks::correctiq_auto
	This block to removes that center frequency IQ DC spike with a slight variation. It automatically calculates the offset then switches to straight DC offset mode to prevent any possible IIR filtering after it's been tuned. However, if frequency or upstream gain is changed, it must retune, so frequency and upstream gain are all taken as parameters and monitored for changes. More...
class	gr::blocks::correctiq_man
	This block provides a mechanism to manually provide a real and imaginary signal offset. Very similar to a complex add block, the block supports dynamic updating on the values. More...
class	gr::blocks::swap_iq
	This block will transpose the I and Q channels (Swap IQ) to correct for spectrally inverted inputs. More...
