/**
 * A simple class encapsulating an attribute/value pair.
 * 
 *  This class comforms to the generic grammar and formatting rules outlined in the 
 *  Section 2.2
 *  and  
 *  Section 3.6
 *  of RFC 2616
 * 
 * 2.2 Basic Rules
 * 
 *  The following rules are used throughout this specification to describe basic parsing constructs. 
 *  The US-ASCII coded character set is defined by ANSI X3.4-1986.
 * 
 *  *     OCTET          = 
 *     CHAR           = 
 *     UPALPHA        = 
 *     LOALPHA        = 
 *     ALPHA          = UPALPHA | LOALPHA
 *     DIGIT          = 
 *     CTL            = 
 *     CR             = 
 *     LF             = 
 *     SP             = 
 *     HT             = 
 *     <">            = 
 * 
 * 
 *  Many HTTP/1.1 header field values consist of words separated by LWS or special 
 *  characters. These special characters MUST be in a quoted string to be used within 
 *  a parameter value (as defined in section 3.6).
 * 

 * 
 * token          = 1*
 * separators     = "(" | ")" | "<" | ">" | "@"
 *                | "," | ";" | ":" | "\" | <">
 *                | "/" | "[" | "]" | "?" | "="
 *                | "{" | "}" | SP | HT
 * 
 * 
 *  A string of text is parsed as a single word if it is quoted using double-quote marks.
 * 
 *  * quoted-string  = ( <"> *(qdtext | quoted-pair ) <"> )
 * qdtext         = >
 * 
 * 
 *  The backslash character ("\") MAY be used as a single-character quoting mechanism only 
 *  within quoted-string and comment constructs.
 * 
 *  * quoted-pair    = "\" CHAR
 * 
 * 3.6 Transfer Codings
 * 
 *  Parameters are in the form of attribute/value pairs.
 * 
 *  * parameter               = attribute "=" value
 * attribute               = token
 * value                   = token | quoted-string
