Easily extract and access columns from a csv file

Keep in mind that the indexes in the results have the same sequence as in the find_this variable:

var clean = true
var find_this = []string { "Name", "Date", "Counter" }
var header_row = []string { "Counter", "Name", "Date" }

c, i, _ := csvtools.FindColumns(find_this, header_row, clean)

Result will be:

[ "Name", "Date", "Counter" ], [ 1, 2, 0 ]

Type: []string
A slice of columns to find. If empty, module will take all the columns available in the header_row

Type: []string
A row from csv file that you think is a header

Type: bool
Exclude non-existent columns from the results

// clean = false
[ "Name", "NonExistent", "Counter" ], [ 1, -1, 0 ]

// clean = true
[ "Name", "Counter" ], [ 1, 0 ]

Returns a column index by it's name. If column does not exists, returns -1

i := csvtools.IndexByName(column_name, mapped_list)

Type: string
Name of the column you are looking for

Type: map[string]int
A row from csv file that you consider a header
