LOBSTAHS 1.1.2

Bioconductor devel release v1.1.2.

More straightforward custom database generation: The database generation function generateLOBdbase has been altered to allow users to add their own new lipid classes and compounds with much less hassle. Addition of most new lipid classes and individual compounds will now require no editing of source code. Instead, users seeking to add their own new compounds and lipid classes to a custom database need only specify values for two additional elements in the basic component matrix (https://github.com/vanmooylipidomics/LOBSTAHS/blob/master/inst/doc/csv/LOBSTAHS_basic_component_matrix.csv) prior to calling generateLOBdbase. Instructions and an explanation are now presented in a revised vignette: https://github.com/vanmooylipidomics/LOBSTAHS/blob/master/vignettes/LOBSTAHS.Rmd

New lipid classes: Release 1.1.2 also includes support for several additional lipid classes, including glycosphingolipids and betaine-like lipids. Data for several of these classes was incorporated from results published in Hunter, J. E., Frada, M. J., Fredricks, H. F., Vardi, A., and Van Mooy, B.A.S. 2015. Targeted and untargeted lipidomics of Emiliania huxleyi viral infection and life cycle phases highlights molecular biomarkers of infection, susceptibility, and ploidy. Front. Mar. Sci. 2: 81; doi:10.3389/fmars.2015.00081
