_D_e_s_c_r_i_p_t_i_o_n:

     This is a utility function to verify user input. It checks whether
     a given annotation package provides a required environment.

_U_s_a_g_e:

     checkannotationpackage(X, Y)
     checkgoannotation(X)
     checkchrannotation(X)

_A_r_g_u_m_e_n_t_s:

       X: Package name 

       Y: Name of one or several environments as a character vector. 

_D_e_t_a_i_l_s:

     The function tries to load the package and subsequently checks for
     the presence of the specified environments in that package. If any
     of them are not present the function will return 'FALSE'.
     'checkgoannotation' and 'checkchrannotation' directly check for
     necessary environments with gene ontology information or
     chromosome information.

_V_a_l_u_e:

     'TRUE' if the package contains the required environment or 'FALSE'
     if the environment cannot be found.
