Updated chebellipseplot to properly handle some obscure input argument sequences that are documented as possible in the help text. Fixed a bug caused by passing in a empty chebfun and requesting a figure handle as output. Removed text from the description that says quasi-matrices are supported.  They are not as the code throws an error when it detects a quasimatrix or array-valued chebfun.
