In Vincent-AC/wellexplainer: Helper functions for MIC and Checkerboard experiments

Generate a PDF with CB raw results, with each plate and CB results

`title`	Title of the PDF file
`data_file`	Path to the output from the plate reader
`negative_control_col`	Number of the column that contains the negative control. Defaults to 12
`positive_control_col`	Number of the column that contains the positive control. Defaults to 11
`lowest_conc_col.A`	Number of the column that contains the lowest concentration of ATB.A Defaults to 10
`lowest_conc_row.B`	Number of the row that contains the lowest concentration of ATB.B Defaults to 1
`number_of_lines`	Number of lines used by plate. Defaults to 8
`knit_root_dir`	Directory where the report should be knitted (using knitr) Defaults to the current working directory
`output_dir`	Directory where the PDF should be saved. Defaults to the current working directory
`max.conc.A`	vector giving the maximum concentration of antibiotic A.The first element the vector corresponds to the max concentration of antibiotic A for the first sheet.
`max.conc.B`	vector giving the maximum concentration of antibiotic B.The first element the vector corresponds to the max concentration of antibiotic B for the first sheet.
