+Description: Implements the Generalized Method of Wavelet Moments with Exogenous Inputs estimator (GMWMX) presented in Cucci, D. A., Voirol, L., Kermarrec, G., Montillet, J. P., and Guerrier, S. (2023) <doi:10.1007/s00190-023-01702-8>.
              The GMWMX estimator allows to estimate functional and stochastic parameters of linear models with correlated residuals. 
              The 'gmwmx' package provides functions to estimate, compare and analyze models, utilities to load and work with Global Navigation Satellite System (GNSS) data as well as methods to compare results with the Maximum Likelihood Estimator (MLE) implemented in Hector.

 - Modified how is inverted the Sigma matrix in estimate_gmwmx() by now using ltsa::TrenchInverse to exploit toeplitz structure of the matrix. 
 - Modified how is computed the Wavelet Variance of the GLS residuals to be performed on the available wavelets coefficients in presence of missing observations.
 - Corrected bug in estimate_hector() that led to non-existent names for the vector of estimated functional parameters, causing problems when printing the estimated model.
-- Corrected bug in estimate_hector() that provided the wrong value FullCov to the argument LikelihoodMethod for Hector ctl file. The default is now set to AmmarGrag and the user can specify it with the new argument likelihood_method of the function estimate_hector().
