(1) without re-parameterization
(2) bound for alpha_c is changed to [1/bound.alpha, bound.alpha], where default value for bound.alpha=6
(2) bound for alpha_c is changed to [1/bound.beta, bound.beta], where default value for bound.beta=6
# Version 0.2.0 (Oct. 12, 2021)

(1) add 'wmat' (responsibility matrix) as output to 'eLNNpairedCov'
# Version 0.1.7 (Oct. 9, 2021)
(1) rename 'getMemFunc' as 'getMemFunc2' and define 'getMemFunc' based on maximum of responsibities per gene

# Version 0.1.5 (Oct. 4, 2021)
# in 'getIniParaEst', added 0.001 to abs(muhat) to avoid log(0)
#
# Version 0.1.4 (Sept. 30, 2021)
