     This function function retrieves features representing a certain
     gene given a gene symbol array identifier

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

     getFeature( symbol = NULL, array = NULL, type = NULL, mart = NULL)

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

  symbol: gene identifier

   array: array identifier only to be used if gene identifiers are from
          affy arrays. An overview of the accepted identifiers can be
          obtained with the function: getAffyArrays()

    type: type of input identifier, this is either locuslink, embl or
          refseq.

    mart: object of class Mart, containing connections to the BioMart
          databases.  You can creat such an object using the function
          martConnect.
